Side-by-side
WordPress
The world's most popular CMS
WordPress powers over 40% of the web. Massive plugin ecosystem, theme marketplace, and decades of community support — but heavy, plugin-dependent, and expensive to keep secure.
Pros
- +Huge plugin ecosystem
- +Thousands of themes
- +Decades of community
- +Low learning curve for admins
Cons
- −Plugin security risks
- −Slow without caching
- −PHP-based, dated stack
- −Plugin subscription costs add up
Substack
Newsletter + light blog
Substack dominates email-first publishing with built-in subscriptions and discovery network. Takes 10% of paid subscriptions. Limited blog/SEO features.
Pros
- +Email delivery included
- +Subscription billing built-in
- +Discovery network
- +Simple writer UX
Cons
- −10% take rate on paid subs
- −Limited SEO/blog design
- −No custom domain on free
- −Locked into their platform
Which should you pick?
Choose WordPress if you're non-technical teams wanting maximum flexibility.
